Mechanical gills, installed along the sides and back of the recipient's neck, allow the cyborg to breathe underwater for a limited span of time. The gills seal shut when not in use, but telltale lines still remain.

Benefit: The recipient of a gill enhancement can breathe underwater for up to an hour. After an hour has elapsed, his gill implants must be flushed with air for ten minutes. Failing this, the character will begin to drown unless he can hold his breath long enough to flush his implants.
